The bike is pretty new. The chain is loose and when it's on the small chainring the chainslap hits the chainstay and is chipping away at the carbon.
Also while riding over rough areas the chain will often slip off the big chainring to the small or off the small completely. LBS tightened the B adjustment screw and it helped slightly with the slippage. They said they could possibly take out a link but were worried about shifting issues.
Anybody else have this problem?
